Got Questions About Solar?

We know choosing solar is a big decision, and you probably have lots of questions, from how much solar costs in Wanaka and Hawea, to whether panels work in winter, or if a battery is worth it for your home.

Our FAQs cover everything you need to know about panels, batteries, EV charging, installation, and more.

Going solar helps you reduce your power bills, shield against rising electricity costs, and lower your carbon footprint. Solar also increases property value and gives you more independence from the grid. In the Southern Lakes, solar is a smart, sustainable investment for families, lifestyle properties, and businesses.
We design and install:
- Grid-tied solar systems that connect to the power grid.
- Hybrid systems with batteries for night-time use and backup power.
- Full off-grid solar for rural and remote properties.
- Every system is custom designed for your home or business in the Wanaka–Hāwea region, ensuring maximum efficiency, durability, and long-term reliability.
The cost of solar varies based on system size, battery storage, and add-ons like EV charging. At Hawea Solar, we tailor every system to your property. Our Sigenergy hybrid systems are modular, so you can start small and expand later. We offer free on-site consultations in Wanaka, Hāwea, Cromwell, Luggate, and Queensberry so you’ll know exactly what your solar investment will deliver.
Yes. Modern solar panels still generate electricity during cloudy weather and shorter winter days. While output is lower than in summer, a well-sized solar system in Wanaka or Cromwell will balance seasonal variation and meet your energy needs across the year.
High-quality solar panels are warrantied for 25 years and often last much longer. Inverters usually need replacing after 10–15 years, while batteries last about a decade depending on use. By choosing premium equipment, your solar system can keep delivering savings for decades.
Standard grid-connected solar systems automatically shut off during an outage to protect line workers. To keep your home powered in a blackout, you’ll need a solar battery or hybrid system. With a Sigenergy battery, you can keep essentials running — from lighting to fridges — and enjoy greater energy independence.
